Using a 16gb iPhone 5 for ~1 week & I'm very happy with it if not for the following problems: I'm having some artifacts popping up on my screen (vertical mode, just below the first line of the QWERTY keyboard). Happens for a few seconds, then goes away. I don't see it while gaming so I'm a bit confused as to why it happens. Battery life is abysmal too; went from 100% at 1PM to 1% at 8PM, although some gaming was involved. On the other hand it likes to randomly stop charging and says that "accessory not supported for charging" when it's plugged in my computer or dock (that has a USB for charging iPad's)... I would go to an Apple store, but my issues are very intermittent and proving that battery life goes away fast is very difficult. Any ideas of what I can do? Anybody else having similar issues?
